Patent GB-281615-A (GB)
IPC: G03B31/00
Filed: 1927-10-12
Abstract: 281,615. British Thomson-Houston Co., Ltd., (Assignees of Hoxie, C. A.). Dec. 2, 1926, [Convention date]. records, combined photograph and kinematograph. - A combined pictorial and sound record is produced by first producing negatives of the two records on separate films selected as regards the sensitizing emulsion to suit the different nature of the exposures and combining the two negatives on a single positive film. For the picture negative, a. rapid emulsion is necessary in which the sensitive element is in relatively coarse grains. For the sound recorda relatively fine grain sensitive element is employed whereby " ground noises " are avoided. The two negatives are combined on a single film, which may be similar to that of the sound negative, to produce a positive film. One method of effecting this consists in first copying the picture negative 14, Fig. 3, on to the positive film 22 by running these two films together with a transparent film 18 having a blackened strip 19 past a beam of light from a source 23, and then copying the sound negative on the strip previously marked by the strip 19 by again running the positive now associated with the sound negative, and with a film which is blackened opposite to the picture strip past the source 23. A modified form of the apparatus described in Specification 180,296 may be used to produce the sound negative.

[Also in Group XL (a)] In a travelling wave or other high-frequency electron tube arrangement in which the beam is focused by a tubular permanent magnet or bar magnets 7, 8, Fig. 4, a flux guide 3 associated therewith is widened at one end 3, and the junction between the wide and narrow parts is an annular portion 2, the reluctance of which is higher than necessary to cause the surplus magnetic lines of force to strike the annular portion at right angles, and a magnetic shunt 10 is provided in the vicinity of the annular portion 2 to reduce the reluctance of the junction. The shunt comprises one or more discs 10 of soft ferromagnetic material which ensure that the surplus magnetic field lines strike the junction at right angles so as also to avoid distortion of the magnetic field which would otherwise be caused by an aperture 4 in the magnetic guide tube 3 for the attachment of a feeder line. The thickness and/or external diameter of the discs can be graded to get a step-by-step variation of the reluctance by interchangeable discs of different thickness or external diameter. Alternatively a number of discs can be disposed one upon the other or one within the other, the external diameter or thickness of which can be varied in steps by the addition or removal of discs. The distance between a disc 10 and annular portion 2 can be varied by a suitable adjusting device.
